Perfect enforcement isn’t required, neither is a ban on DIY solutions. The intent is to prevent normalization. Laws against murder don’t prevent all murders either.

Someone wearing weird 3D printed camera glasses is going to be obvious. Someone with the skill to disassemble a tiny glued together smart glass frame, bypass any hardware protections, and flash a custom OS will be rare, and they’ll get caught anyway when they “accidentally” wander into the women’s locker for the third time.

I don't want people to have to know how to solder to install an open source OS on their personal computing device. That sort of thing should be normal and easy.

So yeah, I guess as long as you're okay with a law like that potentially becoming very easy to bypass then I don't have a problem with it. But I think once things start going down that path, most people aren't going to be satisfied with leaving it at that; they'll hear about a bypass and start pushing to restrict the freedoms that enabled it.
